A Framework For Secure Applications With Qos, Ajay Kanagala Jan 2002

A Framework For Secure Applications With Qos, Ajay Kanagala

UNLV Retrospective Theses & Dissertations

In this thesis we propose a solution to support Quality of Service (QoS) network communication transactions modeled on differentiated services and economic principles. We propose an enhanced user-level negotiation protocol where transactions are accomplished in a secure mode and where resource allocations are simple and fair. With the availability of inexpensive network monitoring hardware, any issue dealing with network security becomes a priority. Current networks must support multiple levels of service over a single network connection. Differentiated levels of service create new resource management problems for network middleware. Just as a first class passenger is willing to pay the premium …

A Noise Detection, Noise-Motion Separation And A Cancer Recognition Theory And Algorithm, Alexander Popovich Jan 2002

A Noise Detection, Noise-Motion Separation And A Cancer Recognition Theory And Algorithm, Alexander Popovich

UNLV Retrospective Theses & Dissertations

In this thesis we describe a noise detection and a motion-noise separation algorithm, as well as the stochastic properties of the noise. The difference between corresponding pixels subject to one type of noise, of two frames, has mean vector equal to (0,0,0), and variance covariance matrix with relatively small variances, for the (R, G, B) difference values. The other type of noise is a result of disturbance of the light equilibrium due to motion in neighboring or nearby pixels. In this type of noise the mean of the difference is non-zero. Every pixel not included in the one type of …

United States Post Gulf-War Policy Toward Iraq: A Systemic Assessment, Amanda Christine Ringelberg Jan 2002

United States Post Gulf-War Policy Toward Iraq: A Systemic Assessment, Amanda Christine Ringelberg

UNLV Retrospective Theses & Dissertations

This thesis proposes that US policy is structurally flawed toward Iraq and the Middle East in general. This structural flaw in US policy-making is a result of ignoring the regional considerations of the Middle East as a subsystem. Current US strategy toward Iraq is doomed to fail because of the unique structural considerations in the Middle East and the failure of policy-makers to recognize them; The thesis begins with a theoretical examination of the Middle East subsystem, based on principles from international systems theory. Several patterns of regularity that define the subsystem are then outlined. An assessment of US goals …

Exploration Of The Nature Of The Work Done By United States Marshals Service Employees In The District Of Nevada, Michael Robin Schlaerth

UNLV Retrospective Theses & Dissertations

For the first time in its 212 year history, the United States Marshals Service created a position for employees specifically designated to assist district offices experiencing administrative and operational problems. This move was promoted by a recruiting session in April of 2001 which was designed entirely to train individuals for the job entitled GS-082. This move is the result of the agency's overall need for more labor. However, while these agents carry the title of "Deputy Marshal", they do not require the same intense training of the standard GS-1811 agents, as their duties do not demand it. Employees in the …

Negotiation And Autonomy In A Fast Food Restaurant, Eric Orion Silva Jan 2002

Negotiation And Autonomy In A Fast Food Restaurant, Eric Orion Silva

UNLV Retrospective Theses & Dissertations

This study is an attempt to apply the negotiated order perspective to the analysis of the lived experience of workers in two franchised fast food restaurants. Drawing primarily on the work of Anselm Strauss (1978) and D. H. J. Morgan (1975), I have examined data taken from auto-ethnographic and overt observation. I found that workers in different negotiation contexts would use implicit and explicit negotiation to achieve internal and external goals. Worker's negotiation strategies depended on the actor's individual proclivities and their interpretation of the negotiation context. Issues subject to negotiation included wages, the schedule, the amount of effort expended, …

Modeling Image Databases Using Xml Schema, Min Xu Jan 2002

Modeling Image Databases Using Xml Schema, Min Xu

UNLV Retrospective Theses & Dissertations

This thesis presents a model for still images in order to support content-based querying and browsing by hierarchical tree structures and object relational graphs. We use the extensible markup language (XML) schema to illustrate and exemplify the proposed model because of its interoperability and flexibility advantages. Of primary interest is the notion of complex types and referential integrity to fully describe the physical and semantic properties of images. XQuery is used to support query processing. We further show how these complex types of XML schema can be used to overcome the shortcomings of reported image database descriptions in the literature.

Self-Stabilizing Wormhole Routing, Anthony Brandon Kenitzki Jan 2002

Self-Stabilizing Wormhole Routing, Anthony Brandon Kenitzki

UNLV Retrospective Theses & Dissertations

Parallel and distributed systems are composed of individual processors that communicate with one another by exchanging messages through communication links. When the sender and the receiver of a message are not direct neighbors, intermediate processors must cooperate to ensure proper routing; Wormhole routing is most common in parallel architectures in which messages are sent in small fragments called flits. We assume that each processor will contain a single fixed-size flit buffer for each incoming link. A processor must forward the flit in a given link buffer to another processor before receiving another flit on that link. This permits messages to …

The Nightingale Sings Anew: The Appropriation Of Antiquity In Virginia Woolf's "The Waves", Neta Luree Hoff

UNLV Retrospective Theses & Dissertations

This thesis considers the impact of classical antiquity on the literary aesthetic of Virginia Woolf by focusing on the educational and theoretical assumptions that allowed Woolf to create her most experimental work, The Waves. Inspired by her brother Thoby Stephen and her tutor Janet Case, Woolf enjoyed a very strong and fertile relationship with the writers of antiquity, and she continued to return to them throughout her life for both conceptual and structural models. In her essays on the Greeks in particular, Woolf praises the ancients for achieving those things that she so longs to see accomplished in the works …

Domestic Violence Counseling Techniques: Indicators Of A Change In The Philosophy Of The Movement Against Domestic Violence, Loretta A Klem

UNLV Retrospective Theses & Dissertations

The movement against domestic violence began as a grassroots effort to eliminate and to prevent the abuse of women. In the beginning, workers in the movement placed great emphasis on societal causes and solutions to the problem and great strides have been taken toward this end. However, over the last twenty years, the movement has placed greater and greater emphasis on individual counseling techniques based on a humanistic approach of individual accountability and responsibility, resulting in the placement of blame for the abuse on the victim; In group counseling sessions there is very little discussion of societal conditions, and no …

Evidence For Virgin Anasazi Presence In The Las Vegas Valley And Adjacent Areas, Susanne Janine Rowe Jan 2002

Evidence For Virgin Anasazi Presence In The Las Vegas Valley And Adjacent Areas, Susanne Janine Rowe

UNLV Retrospective Theses & Dissertations

Olivine-tempered ceramics are a characteristic artifact of Virgin Anasazi culture. The ceramics are found in the Las Vegas area, more than 70 km west of permanent Anasazi settlements in the Moapa Valley. Little is known regarding Anasazi utilization of this area, since most investigators have focused on the permanent settlements. I examined 25 ceramic assemblages from the Las Vegas vicinity, calculated the frequencies of olivine-tempered sherds in each, and noted the geographical distribution of the wares. The evidence does not support down-the-line exchange, but shows concentrations of olivine-tempered wares in the north Las Vegas Valley, Paradise Valley, and further west …
